Which one of these boards..

I've been surfing on a bic 7'3 now for a while and I'm quite confident whith it, fast on my feet and pretty good bottom turn. However, i feel it's a bit hard to make a top turn whith it and it feels heavy somehow. I would like something that turns easier and is a bit more lively but still easy to catch small mushy waves with. I live in sweden so the waves tend to be not clean at all and quite hard to catch since they seldom have a good wall.
I'm chosing between staying with the one I've got aor getting one of these boards: (I'm 5'7" 140 lbs)
1, NSP fish 6'4 Nose 15 5/8", Mid 20 3/4", Tail 15 5/8", Thick 2 5/8"
2, NSP 6'8" funboard Nose 15 3/4" Mid 21", Tail 14 1/2" Thick 3"
3, Custom surfboard 6'0" Retrostyle twinfin with widesplit tail (www.nordsurf.se) Nose 16 1/4" Mid 21", Tail 15" Thick 2 3/4" with fcs fins (mrx twin setup)
What would you get?
I don't think a smaller board would be a problem if it's not harder to catch waves in the poor condition I often have to surf in. Lot's of times it's onshore but it's better than nothing. Sometimes it can get quite good.
Thanks a lot!
