hehehe, the Ko Adang trip is just a suggestion :)
As for PJ, i propose 4th la..so that we can get ample rest on the 5th before going back ler.. :)
According to A Cong, 18th will have strong running currents, thus 300grams also maybe tak cukup ler.. :)
For this Jarak trip, we will be hitting some shipwreck at 82meter depth. 82m x3.3 you get 270feet. Rule of the thumb is that 100feet, use 100grams. This doesnt count other factor like strong current and such. At times, 100feet you might need to use 200grams due to the current, or you want the jig to fall in faster :)
The 4th is slow current thus we can use lighter jigs like 200~250grams, but certain part of the area you might need to use 300grams. So be prepared for 80~300grams jigs.
