Re: 6SN7 - what should I use it for? :-D

Re: 6SN7 - what should I use it for? :-D
I've done some maths and designed a LTP PI around this tube, but I've noticed that a lot of schems and the app note for the tube use a totally different plate load resistor value.  
I've used 22k but the app note uses 100k and so do a few Ampeg and Gibson schems. What's the deal there? Is there any advantage/disadvantage in using either value...  
also, it's a 6SN7-GTB (glass tube) so I decided not to stick it up my butt after all. :-D
