for the 40 version the 61 sf or fx will be perfect, and for the 70 version the 91 fx is just ballistic!
also the new versions by tmpro are 100% better i'm going to do a review on both the 40 and 70 size very soon!
Thanks cajun! yeah definately you need to come here soon to have a great time =) or i go there LOL
