I'm looking for some advice from the kiltmakers on here who might have had experience with the Robertson Modern Red sett (Lochcarron Strome)

The sett is slightly unusual in that there is a reversed repetition making a whopping 13" total sett size rather than the more normal 7". On the reverse sett the blues and greens reverse so we get BLUE red green red black red green red green red black GREEN red blue

My first though is to make some pleats marginally deeper to compensate so that BLUE goes to GREEN and vice versa in every full repeat. Has anyone else got any ideas that might be better?
