I actually think it would be an excellent move for the Club and Elding. For our part we get a striker of proven abillity and experience. In Elding's case it seems that he has lost favour at Grimsby, so what would he have to lose by putting himself in the shop window at Boston? If he plays to his potential I'm sure he would be very succesful at this level and alert conference/League 2 clubs that he still has what it takes.
I remember Adam Boyes doing something similar a couple of seasons ago and getting signed on at Barrow the following season. However, if as some are saying Anthony doesn't want to come, like Spriggs, I'd sooner not have him. We only want players signing who want to be here in my opinion.
