I'm heading to the ocean next month and wanted to try the "bubble rig." I was looking for recommendation of the size of float that is necessary. One site referenced two inches. I was able to find a store that had a 12 pack of 1-3/4" bubbles for $2.99. Alternatively I can order one 2-1/2" for $0.96 site to store from Walmart. What do you think? Are the 1-3/4" big enough or will I wish I would have gotten the larger ones? Thanks.
