bob and drew, thanks. 11x14 overall kit should be about twice bulier/heavier compared to 8x10. im not into holywood style studio or retouching. just platinum contact prints that fascinate me. 8x10 is great in the hand, 11x14 will look better on the wall usually, but the bulk may turn a limitation during the principal photography.
jonielvil, thats an interesting point. the lens issue can be felt on 8x10 already, and a bit on 4x5 too (even with 150 lens), though not as dramatic as u described in the case of 11x14. i actually like that aspect.
