It depends. I haven’t measured all of them in each putter head but my assumption is that the 3.5 will stay very close to face balanced and as each hosel gets a little shorter there could be a little more toe hang.
The 3.5 will stay very close to face balance and as each one gets shorter they will create a little more toe hang. The 2.5 would create the most toe hang. Again, this can vary depending on the putter and how much they are being bent.
