I suggest using a yellow filter for best results. Experiment with it. The quick prints from C41 processing are ok for proofs but not for the final print. Have fun with it and enjoy the experiments. I too hope to try the new Kodak film whenever it hits the market.
People think the prints are from medium format negs.
The only disadvantage I can see is its lack of archival stability. Peter I've compared two rolls of XP2 film that were identically exposed. One roll was processed at home with Ilford's kit and the other was processed at the local camera store. The roll processed at home had much better acutance and better contrast. The better acutance is probably attributable to the intermittant agitation I used, and the higher contrast to agitation and length of development time.
