You must go and fly in the states. It's great fun and soooo easy. I landed at mccaren Vegas with 150 hours and it was great and very easy.
You must however be very aware ( and respectful) of density altitude. We went from the Vegas (baby) to canyon at 6500'. Landing was fine. On take off there was a board indicating a density altitude of 7,500' due to the temps. I thought no probs, there were two of us in a Cessna 172 xp. Climb rate 1500fpm at ground level, were in clover. I did wonder why canyon airstrip is longer then heathrow. Anyway I was ace, this was not going to be a problem. At 12 noon and 35deg we lined up ( you can guess where this is going). Half way down the runway (5000' gone) we hit 50kts. Not looking good. At 7000' we hit take off speed and climb at 100 fpm. We made (just)it but isn't it amazing what density altitude means!!!
