The ebay link 2 above..... someone's been ripping off stores again, and his buyer.. I mean £22 for that??? Does his buyer know it's just a crappy nylon bag??!
Putting the topic back on original track..... Anyone will have a certian amount of natural ability in different areas. The less natural ability you have the better you'll have to prepare for flights. You may be great at general handling but fall down on instrument flight or navigation. You may not be very good at the general handling but make up for a lot of it by having a competant and confident manner in the aircraft along with good spatial awareness. At EFT level there is more focus on someones ability at instrument flight and nav than on general handling when it comes to streaming them. Of course they will have to do well in all areas.
Ultimately work your hardest and you won't be left thinking 'if only...' if you don't get sent where you want.
