a few points here;
your mate needs to decide what type of bike he wants, if he's staying with full suspension then his choices of boutique are restricted anyway.
then he needs to set his budget, if he's got £7000 the world is his oyster, if he got £700 quid then… well the world is not his oyster.
what does he do with his bikes, does he like trying different parts and playing in the garage or does he just want to buy it, ride it and put it away until next week?.
orange hardtails are manufactured in the far east whilst fs are manufactured in halifax.
are all bike frames really welded by hand?
we went out yesterday, at one point there was 20 of us, a mix of mass produced, boutique, old, new, hardtail, full suspension and a raleigh! the first one to reach the top of the climbs and the bottom of the descents was the rider with the strongest legs and biggest bollocks (or crapest brakes!!!), nowt to do with the bike.
mainstream manufacturers will change their designs annually because the marketing department want to sell more (that's common to all manufacturing, not just bikes) and we, the consumer, must have the latest model. orange have only tweaked the five a bit because it was good from the start, their approach was to add to the range, blood, st4 etc
