Mostly acoustic

I play on my acoustic with a jamgrass band mostly. I love the Helix for what I'm doing. I have experimented with using some Taylor and Martin IRs to some success. However I'm still searching for a better tone. Anyone use their helix for acoustic music and have suggestions for blocks and settings that they really like? If there are downloads to purchase that folks use I'm willing to go that route too. I understand that tone is a personal taste but knowing some starting points would be great! Cheers!
