my choice is an easy one.
sail.....5.0m 08 Gaastra Vapor
board.....88litre 05 Anders Brindall slalom board
fin..... probably my 30cm leading edge weed fin or my 25cm carbon pointer
would not get much sailing in, but in heaven when wind hits 20 knots plus.
I only use 1 board and 1 sail 80% of the time anyway... either there's enough wind to plane or there's not.
Sail.........8.5m Ezzy Freeride (2010)
Board.......Fanatic Falcon 145 (2007/8)
(I refuse to cave in and buy BIG gear) 
...all the other stuff I have in storage - the 3.6, 4.0, 5.0, 5.7, 5.8, 6.9...well, that's just for show 
my choice.
A 6.7m race sail, F2 SX68 (105LX68cm) 34cm weedie. This combo is good from 15-30knts if you have to.
Have only been using one board for the past few years in up to 30 knot winds: (somewhat out of control in 30kt over choppy water!)
2009 Fanatic Hawk 93 (with std 28cm fin)
2011 KA Koyote 5.9 (sailed 90% of the time since getting it last Dec)

I think we all know what your favourite combo is lao shi!
This season I have only used one sail and board, aside from one or two occasions. I have plenty of sails but I love this one so much I even use it when I should use something of a different size.
85L Sonic, 5.7 Koncept,
My favourite fin is lao shi's slightly less than 30 cm G11 pointer 
I'd consider all my bad karma had caught up with me!
It would have to be a choice between wave sailing and speed sailing, don't know how I'd make that decision, have to cut me down the middle I think.
Ahh well that would be the same as what i have been sailing for the last year,
5.3 Severne blade and a RRD wavethruster 76 with the stock fins.
well only had the rrd a few weeks but B4 that it was a JP radical wave 74. the RRD is sheetloads better 
Gotta set the blade on a 95% carbon powerex rdm too, man i love that mast.
I would go to the Netherlands and only use my NP RSR EVOII 4.7,JP Speed 45 with my KA Lockwood SYM 23cm fin
current Reality -hypersonic 105 and NP 7.5 V8
Dream- Manta 64/65 - the gold one, Severne 7.0 Reflex II, Delta fin
JP 99 Single Thruster
+
5.8 Neil Pryde Atlas ... (or maybe 5.4)
That's what I have been using all summer... so I guess in essence that's all I need anyway.
Reality = 7.5 Ezzy Freeride + Kona 1
Dream = 6.5 KA Kult + Exocet/Kona 11.5 (but 7.5 Ezzy will most probably still be used most)
That's just too hard a proposition - it would be easier to decide on which one of my 4 kids I would pick.
It's a good thing we're not trying to form a concensus.
I guess that's why there is such a huge range of gear available.
We all want something different.
Naish Koncept 110
Naish Force 6.2
Naish 100% 430rdm
29cm Select B&J fin
Mauisails carbon wave boom
North Shox
Would cover 15-30 knots for me, probably more if required.
