I recently got the Black Widow one you mention. I think it is a pretty good rack and it does have an extra long loading ramp.Short answer is I prefer the non tilting type. I got this one because I had a non tilting one before but the break over angle was too much so I wasn't able to load my Ruckus on it. Now after having used this one I will probably go back to what I had before but find one with a longer ramp.
What I don't like about it:
-It is very heavy to lift up the back end once the bike is on the ramp. Imagine trying to lift 100-150ishlbs with 1 hand starting from 2 inches off the ground while trying to line up the hole to push a pin in with the other hand. If you have a bad back this would be brutal. You need to bring someone with just to help lift the carrier. They should have designed it with the pivot point in the middle but because it is so far to the left side a lot of the bikes weight has to be picked up when lifting it into place.
-The TW is wider than other bikes and this causes the foot peg to hit the non tilting part of the carrier every time you lower or raise the bike. So before you do either you have to release the tie down so the bike is leaning away from your vehicle.
-The carrier bounces around a lot. It makes me a little nervous. I'm constantly looking back to check if everything is ok. The excess movement is caused by the pivot point and the pin. There is no way to tighten it.
-Its a real pain to change the front tire mount to adjust for different wheel sizes.
-The price. Luckily I found this one on Kijiji and it had only been used 2 times. The guy said he paid close to $850 delivered to his house. I only paid $275 so I'm not too upset about it. I can always sell it for what I paid. But if I had of paid $850 for it I wouldn't be happy.
What I do like about it:
-It tilts. But if you don't have a scooter it's not really necessary.
-The way the front tire is held in place by the frame of the carrier. Makes it a little easier to attach the tie downs while trying to stop the bike from falling over.
I will be looking at picking up once of these at some point to replace the tilting one.

Hope this helps.
