After you find the kit that suits you my only piece of advice is "oil your filter, oil your filter, oil your filter" and make sure you have a few battery packs which you can change out after each heat. Zip Tie everyfuel line to its connection if running nitro and lock tight any metal screws that fasen to aluminum. Last but not least if you by one roller then you might as well buy two, the second is for parts. The rest is all preference and performance.
