Yes, we switched over to TTSX's or E-Tips a few years ago when shooting monos, since we've never had any failures to expand with either, unlike the original TSX's. I've also been happy with my limited experience with Hornady GMX's and Curtting Edge Raptors.
As Klikitarik pointed out in his post, the biggest problem you're going to run into with the monolithic bullets is failure to expand. The plastic tipped versions seem to have solved that problem.
