I would check into a Rhino tube. A buddy of mine uses one in his encore and it is just plain awesome. Everyone on the net says the same. A little pricey at about 100 bux but if you want the pattern its worth it. I am using an Indian Creek in my 835 and it does pretty good. I have been thinking about swapping to the 870 though and if I do I will be getting the rhino as well.
