I own both a 1098 and a monster. I think they are different bikes that serve a different purpose.
In my opinion if you buy monster and change it to clip-ons you bought the wrong bike. and again change a sportbike to upright - you bought the wrong bike.
I love both bikes and would hate to only own one but If I had to choose the monster would win for it's versatility and ability to do all things well (was that redundant?)
So no, I don't think you are wrong to fear the 1098 riding position. I'm also 48, I can ride the 1098 all day but I prefer the monster.
Out of the choice for the 1100 or the Tricolore I would buy the tricolore because it has a superbike motor. But that's just where I'm at with my riding, I want a radical hooligan bike.
I don't hate the new monster in fact I like it better than the old monster and I think the 1100 is going to be a great bike for a lot of people.
If you don't need or want the most power possible the 1100 may be just the ticket for you. I think they will ride and handle very similarly, the tri will just have a little more power, a wider powerband, and run a bit smoother. The 1100 will be less money to maintain.
The choice is ultimately yours I think you need to buy the bike that fits your riding style, the tri if you are a hooligan the 1100 if you are a little more mellow (but still need to throw a wheel up once in a while)
