i would say the c60's if you can shell out. otherwise, C02's then cartels. Might want to check out the Triads too... they have the Cartel baseplate and C02 Highbacks.. so its a mix between the two, literally, ha.
as for park sometimes... anything with a highback will feel cramped when attempting grabs and such.
cartles if you desire flexibility, c60's if you want directness, and then anything in between.
as for boots, can't help there, hopefully someone else out there will
