chele, I am by no means a pro shooter. I think i am decent for my experience level but i KNOW FOR SURE, for me the grip tape makes a huge difference. I personally wont shoot without it. You can even put a small piece on your take down lever if you wish.
If you plan to try it out dont waste your money with talon or the others. Simply go to your local skateboard shop and buy a piece from them. Much cheaper and you can do more than just the grip if you want like the trigger guard or the takedown lever. The one thing i do not like about the talon (kother than price) is it wraps all teh way around your grip in one piece so you cant change backstraps if you want to. Just another option to try. Hope all works out for you. Talon grips=$17 plus shipping Skate shop $7 no shipping
