Good Hopup upgrade?

[Radonkulus]

Hello new to airsoft and this site. Sorry if this has been answered before but I tried the search on the forum and on google and i get really inconclusive information. Just wondering if anyone has experience with the wii tech 70 degree bucking with copper rivet( in stock at mach1 airsoft), the mapleleaf monster 60 degree and the modify flathop with flatnub for .2g bbs.

Thanks I recently got a used cyma mp5sd6 in wonderful condition except for a rip in my hop up bucking. Shooting at 350fps and just hoping for some advice.
I mostly use .25g Elitforce bbs in an indoor setting.

Well i decided to get the maple leaf hopup as it is supposed to offer "r hop" style preformance and i figured for 12$ from airsoftparts.ca why not. If anything i will update once i recieve and test the item.
