Hand warmers chemical (there are disposable ones and shorter warming reusable ones) or electrical will keep the skin tackier and bees wax is ecological. Mark Ellis suggested Pow'r Tac IIRC but the problem for me is that i haven't found a source on this side of the pond yet.
Another thing you could do is to get a super thin yet durable material glove with minimal to no seams and apply rubber cement to it. So far i tried that with a kangaroo skin top fabric inner UGS golf glove that has some seam in the tips of the fingers and the grip was excellent but the added pressure ripped the kangaroo leather and the rubber cement off in one short field practice session. I've yet to apply more rubber cement on just the fabric. It needs to be tried.
Some working gloves could work. Nitrile starts out tacky but dries within a season to not as grippy but ok. There are some gloves that have a grippy rough surface but they come in so many varieties and might not be available the next year so who knows happy hunting on those. Some of those gloves are too thick or stiff to bend around a disc and allow a good grip and some have a too slick hard material. I need gloves for warmth in the colder season and i found Finnish manufacturer of work gloves called Patron (not the Mexi tequila distiller) that made a too thick but great grip glove so i've been thinking of cutting off some of the material. before i do that i'll try to rubber cement some thin fabric only gloves though. It seems that rubber cement cannot take the pressures involved for more than a session but i'm ok with that since i have a tube waiting to dry on its own anyway. So yeah living in a cold wet country makes you try all sorts of wacky ideas.
We've had just below to a little over freezing temps and on Thursday i was throwing gloved first and with two finger power grip to three to four and got slips even with four fingers annied four hours into the session when i was dog tired. Annies need more grip strength than other throws and i had some slips with flat shots especially when i did not concentrate on gripping harder and tried to keep the grip loose and pinch late and was late on the pinch. With that said i got the least slips ever and the hardest average ripping sensations from the fingers with two finger power grip. Which in low to high 30s F temps was previously unachievable for me with FLX discs and now i had C Line and TP plastics that are on the slickest side of the spectrum. Which made me think that i gotta take my MVPs out for a spin.
My grip strength has increased some from working out (yay!) and it does help in eliminating slipping but i have ways to go. MVPs are the acid test for me. It is dry but cold now on my practice field and that makes it easier than normal worst wet conditions though. But i really hope my MVPs won't gather dust for as large part of the year as they have for being too slick to score well and be trusted when it is dry. Who knows with enough toweling maybe wet conditions too will become better with the added grip strength when the temps go up. And now i can keep my electric warmer with me all year round so even rain on a warm day that tends to cool down my dry slick skin to slippy could be countered. Fingers crossed and yes i realize that rain plus electrical appliances is a dangerous proposition. That is why it sits in a ZipLoc equivalent water tight bag already during the winter time. Yup it's gonna snow today and tomorrow here bye bye the first signs of spring
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
