I don't buy the argument for not listening to someones advice just because they sell a certain brand, don't dismiss advice from a dealer just because you think he may be on the make.
entry level reflex wings (revo2/ synth etc) have been around long enough now to be able to form an opinion on them from pilots that have flown them for some time, when deciding on a wing you need to think about the type of flying you are aiming for and if like some people you pick things up quick and will progress rapidly, is your eventual goal to compete or just be casual flyer? are you interested in just a little bimble around the skies every so often or are you going to be throwing yourself into this sport and spreading your wings on big XCs?
Reflex wings with a good speed range are ideal for all round flying, you may fly around most of the time in take off trim and be perfectly happy with that, but if the wind gets up while you are aloft you could find yourself struggling to make progress and its handy to be able to open the trimmers and jog along nicely.
also after your training has finished you may go off and find some flyers local to you who are all on reflex wings, flying with them will be no fun if you are always getting left behind and watching the windsock.
as for the two wings I mentioned, the REvo2 is proberly a bit more sporty and easier to launch, but the synth is a good solid wing too, and its dudek so its made well, both a pretty forgiving and wont get you in too much trouble should you be a bit heavy handed with them.
