I played two more rounds with the Mercy two thirds of the last round in the rain. I can't let my index finger and thumb to be totally loose in putting or it will slip out when wet in 56F. Adding a little gripping strength doesn't hurt my form or results from what i could see in putting. There was a good bit of wind and at times the disc turned 2-3 degrees but so would any other straight to straightish putter have done. More anny experience and for shorter approaches the Mercy turns tight enough for anything but the tightest turns if there is no ceiling. I don't know the exact distance yet where it starts to push through anny but it can do that for a long time given more power. Probably 250' is enough to show pushing through anny. So you would limit what you can accomplish if you carried the Mercy as the sole putter. Hyzers worked beautifully and i was a foot or two short of metal today despite exposing the bottom of the disc slightly to the r>l wind hyzered on purpose. No deviation from the line just the wind pushing the disc sideways. I did see lifting in stiffer headwinds in putts and drives again.
I threw uphill 6' in a tunnel of IIRC 200' throwing to 10' above the 6' risen ground with a flat shot that faded 13-14'. The fade can be significantly less on higher powered and/or lower throws. This shows that it is a fairly straight disc especially at above 200' distances.
