iS133 fin sizes

[Duracell]

Sorry for duplicate post, logging on jumps to different form...

iS133
-------
fin size range described as 36-48
tail width 54.8
sail range 6.5-10.0

In the '07 line up supplied fins and recommended fins have change quite a bit compared to '06 (e.g STs, ST104 '06 was delivered with a 290, now with a 360, K86 with a 300, K87 with a 260)

I'm going to receive my iS133 end of the week and would still like to get an additional fin (should that make sense).

Questions
------------
- wasn't there a rule of thumb, fin size till max tail width?
- fins so different between the years?
- shouldn't a Slalom Pro 52 fit the iS133 with a 9.5 well for early planing (8-12kts)? Shouldn't it help early planing? Maybe you could supply a bit of background information an this subject ('07 boards, tails widths vs. fin sizes, especially for the iS133)?

Thnx

c'mon guys, there are a couple of very valid questions in this thread, I don't think I'm the only one interested in a bit of insight...
