Any advise on straights to buy?

Can anybody give me some feedback on any of those razors.
I'm looking to buy a Otto Busch Weltmeister "Pirola 2, Otto Busch Weltmeister (worldmaster) 194 or 854, 6/8 Heribert Wacker INOX or one of the new forged steel TI's?

TIA

I've got a Wacker and I love it. It is supposed to be one of a six razor rotation but I seem to forget about the other five whenever it is time to select the blade for the day's shave.

I also have a Wacker and think it is a great shaver.

I've got a couple of the Heribert Wacker razors and they are quite nice.

I have heard really really good things about the new TI's so that is probably what I would recommend.
