SLK ultima if you can or the SLK is very good too. They both have a deeper seat and bigger cantle than the K2 and seemed to keep my position much better. Sadly had to sell mine as it no longer fitted the horse either!!
I have the SLK, which i absolutely love. Very comfortable, and keeps my position good. Also when my horse is being sharp, which is quite often, it makes me feel really secure.
Thanks for all the replies, very interesting. Are all SLK Ultima's adjustible, no mention of platinum on their web site, have emailed them to check. Platinum sounds great! thanks
There's also the SL model, it has a flatter tree apparently - my mums horse was too flat and wide for an SLK.
The Platinum SLK is the only one thats adjustable, however ring Albion as I think they can put a new tree in for a large fee. (I think the Platinum change the head plate only).
Also try Saddles Direct, they usually have a good stock of 2nd hand Albions - as some of the previous posts state, horses grow out of them.
We've got a Sue Carson Harmony that's fully adjustable for the horse and rider via the use of Flair, but they can also adjust the width of the tree if needs be. We've already had 3 adjustments over 2 horses by the Yorkshire Rep.
