Generally, I like to take an instructors advice.
HOWEVER, if you are uncomfortable with your current loan, you need to tell her this.
If the cob has a previous history of taking off, and it was not pain related, then there could be a good chance that he may be too much. A couple of rides is nothing compared to full time riding, and he may try to take advantage of your greeness later on, as he did in the riding school, and use it against you.
If your current loan is not suitable, I would suggest you talk to your trainer and explain. There are SO many horses on the UK market at the moment, and with winter approaching prices will drop.
Why do you have to make your decision after two rides? If they are looking to sell the horse, ask for a loan period with a potential to buy. This would be your best bet as a fairly green rider. If you can have him on loan for 2-4 weeks (I'm assuming he is at your yard?) then you will be working him for them, and taking on some financial responsobility.
If you find the horse you currently loan too hot, then I would be hesitant to take on a bolter. Even at my stage in riding, I wouldn't take on a bolter.
I think you need to discuss with your trainer why she thinks the horse you currently have on loan is suitable, and not the cob.
