Trying to multi-table HU/SH, recommended or not?

[NDHand]

I'm currently 8-tabling full ring games with 25% rakeback at party skins. However I got offered a pretty tempting propping deal. As a poker prop I would obviously have to play HU/SH. However, I was wondering how important observation is in HU/SH games. I read in Jason Pohl's article that observation was much more important to win in HU/SH play (whereas tight, solid, straightforward play is usually more important in full ring).

While obviously 8-table propping would be a lot more profitable than 8-table rakeback fullrings, is it realistic to assume I can HU/SH 8-table at a time? Will I lose too much in reads/opponent tendencies? Mostly wondering if anyone else had any experience on the matter and could offer advice on what is the best +EV choice as i'm not sure if 2-3 tables of propping would compensate for my usual winrate/rakeback at fullring 8-tables.
