This is a puzzle following up on my other puzzle The Palindrome loop, using the same shape of loop with a different rule set and solving path -- this time using arrow clues instead of palindromes. Here are the rules:

Standard Sudoku rules apply: 
- standard killer cages rules
- cells separated by the white dot must be consecutive (not all dots are given)

The green loop consists out of a consecutive sequence of standard arrows clues, which must fill the complete loop (there is no gap allowed). The positions and lengths of the individual arrow clues have to be determined. All arrows point in the same direction along the loop (and the orientation has to be determined). In addition, all nine instances of the digit "9" must be placed on the loop. 

For clarification of my probably poor description of the possible arrow sequence, the following example would be a valid arrangement:
