Yes I am very new to crossbows I dont even know why you call them x bows lol. Thanks for the Info on the broadheads I will return them for some different ones. I will call cs tommorow and see what the minimum weight is, but I think I will just buy some 20" as everyone seems to suggest. What are the downsides areto using 20" bolts as to 17" I guesse it would just be a little bit lower fps wich realy dosent matter as the extra mass impackting will make up for it. I am very confused on wich length to go with tho... If I can buy 17 inch would you recomend me going with those over the 20"? Thanks for helping a newb with questions
