Go Steedspeed. I have had both Thunder V1 and now a Steedspeed. I can honestly say I am VERY happy with the Steedspeed mani. I dunno if the Thunder V2 is prone to the same problems as V1 (I would assume its not, however time will tell). I can see parts that MAY crack (I am not saying it is, but I can see where they might, IF they do). The Steedspeed I cant find any place that would crack on it LOL. Both mani's are great, but for me the Steedspeed has the looks (personal opinon) and the style that I like.
