Trunks

I've been wearing swim trunks ever since taking swimming in highschool, i havent swam for 4-5 years but i've worn a speedo when i practiced at a club, and at my meets. Im one of the fastest at the school with a time in the high 30's for the 50 free :laugh2: i know my schools horrible, so since im joining the swim team and wearing jammers, has wearing trunks the whole time sort of acted like a dragsuit or even more drag than a dragsuit? And how much time do you think ill lose when i switch from trunks to jammers / speedos
