I throw a lot of forehand, generally whenever the hole ends to the right (Im right handed). I also throw forehand 400+ on max d. The two discs that I use the most are a max weight Star Destroyer (differnt levels of stability for shot requirement) and a max weight Z nuke.
It really is going to come down to how good and how far you can throw forehand. A destroyer is a great forehand disc (probably the best imo), but if you don't throw atleast 350+ I would go with something slower. My personal preference is heavy star destroyers. The reason is that they tend to be plenty stable for forehand and atleast for me seem to get more distance than a champ. I would not suggest the blizzard because I think it is going to take a lot of forehand experience to be able to throw it with the right amount of power (however not positive, just got one today and haven't had time to test it out yet). If you don't throw 350+ a destroyer will teach you to over anhyzer your forehand which I think is a bad way to learn.. So if you are right around or under 350 distance I would actually suggest a champ wraith, z surge, or maybe a pd to start. This is what I started with. This is counting on normal wind, high wind does require to disc up in stability.
Just like backhand there is good and bad forms with forehand. And just like backhand I suggest learning to control a more medium stability disc to get form down first. Forehand does produce a higher speed release and snap than backhand imo though(with less effort atleast), so instead of recommending a valykrie I recommend a surge or wrath.
Sorry for babbling on, I am a big forehand lover from years of ultimate. So to sum it up, my recommendation is 350+ distance on forehand = 170-174 star destroyer (plus z nuke), 350 or less distance = champ wraith, z surge. Also forehand is just like backhand where you will want to use different stabilitys for different lines and shots.
