I'll take the plunge...Captain Sim 757 Block F - personally I think it's ok!

Pros1. Ground handling characteristics are different from block B2. FMS more fully implemented - has a nice hold feature3. Weather radar is cool4. Overhead switches do stuff now5. Frame rates are ok on a dual core machine with decent memory and a 256 mb video card6. Flight characteristics seem to better reflect loadings than earlier block b - no 6000' fpm climbs at gross weight accelerating any longer (darn!)7. Nice sound setCons1. I experienced a number of CTDs so I think the model is buggy (not too bad, though)2. Gauges are 'Captain-Sim-small' and hard to readOverall I like it - I got the 9 euro update to the existing block b and I'll continue to fly it.I hope others experience with this new package will be similarly successful!
