OK... one thing is, don't expect PG to be like Sepang. Going to Sepang is like going to a 5 star hotel, compared to PG which is like going to 2 star one
Its an old track, surface is rough, some part are bumpy, sand / stones that ur refering to is not really an issue... but generally is not that bad la. Its a really fun track and very different from a sepang experience. Corners are actually misleading. Some look sharp, but in actual fact can tekan, some look like can layan, but actually need more steering input then u orginally anticipated, some corners are really blind and the track changes elevation a couple of times... but after a few laps you'll get use to it and know where u can push and stuff... its fun and reminicent of batu 3..
