Help with espailier tree

Hello there, I am after some adviser with my attempt at a conference pear espailier tree. I'm quite new to gardening and have some good apple tree espailiers on the go which were bought as barefoot unfeathered maidens originally. During winter I spotted some barefoot pear trees in tesco for sale for really cheap, they looked 2 years old with several small branches which weren't trained. I decided to buy one in the hope I could train it into an espailier. I know it's not the proper way of doing it but for the price I thought I would experiment. I removed all but four of the branches, two pairs each 30cm apart. I tied them down at 45 degrees but this summer they have hardly grown out at all - they started to do so, but have now hardened off and stopped. The vertical branch has also done the same. I was worried about transplant failure but there is no reason I could think of as to why it may have failed. Also, a few new branches have started to develop along the vertical branch. My question is this - shall I remove this new growth in the hope that my older tied branches will start to grow again? I shall I keep the new branches and hope that I can use these for my espailier? Thanks for your help!
