The best flashcard to use with dsi firmware v1.4.1

i posted the following in the troubleshooting area of this forum but i think it is relevant to this topic as well.Obviously the firmware on the dsi and dsi xl has just got updated and hopefully more and more flashcards will be made or have updates/kernels created so that they can work with v1.4.1 (U and E versions).So far the list of flashcard that work with the firmware are:EZ-Flash ViiSmart DS (both v1.4.1U and v1.4.1E according to their website)Hyper R4iR4i Gold card (only v1.4.1U? - does someone know/confirm that this can't work on v1.4.1E?)Supercard DSTWO Acekard2iM3i ZeroiplayerDSTTi Card? (can someone confirm this?)(i will update as more come available - if ppl can tell be which ones of the above are proven to work on the US version of the firmware and which the europe version i'd much appreciate it)The question is which of these flashcards so far work the best in all of your experiences (the least bugs, blocks, virus's, least crashing and/or messing up of the ds system, the best running, easiest to use, etc....)many thanks in advance
