step side vs fleet side!!!!!!

[70blazerpickup]

i have a 70 blazerpickup/ trazer what have you. anyways its a 104 inch wheelbace pickup. i have a choise between cutting down a step side bed or putting a head bord on the back half of the blazer body. i was thinking the fleet because there would be more bed space, but step sides are cool looking. the labor aside which one would you choose. by the way my blazer pickup has a 4 inch lift planning on getting Q78 swampers. it has a 12 bolt posi and a dana 44 open nuckle front end wosh will be getting a lock right locker soon. it has a 4 bolt 350 with a 4barrle carb and 3 inch dual exost. to top it off its a 4 speed truck. i just donno what type of bed to put on it. by the way this is my first truck and im only 16 and iv done all the work myself since i was 12. every one please put there 2 cents in on what bed you like and why.
