Delta II tip section weights for sinktips

Some of the more enterprising anglers out there may want to cut and loop a Delta II floating line for sinktips. I’ve produced these two tables to help you decide what weight of sinktips to use. The first table shows the weights of the front sections of Delta II matched to the length of the sinktips of the same line rating (e.g. 7/8 sinktip for 7/8 line) based on the sinktips used on the older Delta Multi-tip lines. They are still available from Airflo.

This first table shows the weights of the tips section from 13’ to 15’ depending on the line:

  • 94 grains for the 7/8 measured at 13' (51')
  • 100 grains for the 8/9 measured at 14' (56')
  • 117 grains for the 9/10 measured at 15' (61')
  • 113 grains for the 10/11 measured at 15' (66')

This range of weights may look odd until we factor in the difference in lengths. The 7/8 Delta II is 51' long and the heavier lines go up in length in 5' increments to the 10/11 at 66'. As a consequence, the front tapers are steeper on the shorter, lighter lines producing tip sections that are relatively heavy in comparison. The old Deltas went from 52' at 7/8 to 57' at 10/11.

Here are the weights of the floater tip sections with all lines weighed at 15' long:

  • 110 grains for the 7/8 measured at 15' (51')
  • 107 grains for the 8/9 measured at 15' (56')
  • 117 grains for the 9/10 measured at 15' (61')
  • 113 grains for the 10/11 measured at 15' (66')

This suggests that all of the lines could handle the 105 grain 9/10 tips, though the belts and braces crowd may prefer to align the line ratings with the old Delta tip ratings.

Here are the weights and lengths of the older Delta Multi-tip sinktips that are still available for sale as replacement tips:

• 77 grain, 13’ sinktips for 6/7
• 85 grain, 13’ sinktips for 7/8
• 97 grain, 14’ sinktips for 8/9
• 105 grain, 15’ sinktips for 9/10
• 115 grain, 15’ sinktips for 10/11
