help please

so i am currently on my first unicycle my parents bought me… a torker cx… that i have been riding for a year and can ride very well. i am now more interested in getting into trials and street riding and am finding it very hard on the cx and know that i need a better uni. if you have any suggestions that would be great. i am also trying to learn 180 unispins and crankflips. so far not so good.,
